Standards-driven Heavy Hex Nut and matched bolting RFQ
ASTM A194 Heavy Hex Nuts
Source ASTM A194 Heavy Hex Nuts for industrial bolting requirements by nut grade, Heavy Hex form, nominal size, thread system, finish, marking, packing, matched ASTM A193 Stud Bolt inputs, material document request and inspection requirement.
WISINE can review inch and metric sizes, UNC, UNF and metric threads, separate nut orders, one-nut or two-nut configurations, matched Stud Bolt orders and custom thread or dimensional requirements according to the purchase specification.
ASTM A194 Heavy Hex Nut Product Scope
This page supports RFQ preparation for ASTM A194 Heavy Hex Nuts supplied according to purchase specification, nut grade, Heavy Hex form, thread, size, quantity, finish, marking, documents and matched bolting requirements.
- Heavy Hex Nut form for standard-specific industrial bolting inquiries.
- Inch sizes, metric sizes, UNC threads, UNF threads and metric threads according to inquiry.
- Separate nut orders, one nut per stud where requested and two nuts per stud where requested.
- Matched ASTM A193 Stud Bolt orders and custom thread or dimensional review where feasible.
Heavy Hex and regular Hex forms should not be treated as interchangeable. Nut form, size, thread and matching Stud Bolt requirements should be stated in the purchase specification.
Heavy Hex Nut Forms and Configurations
Nut configuration should follow the buyer’s purchase specification, matched bolting arrangement and packing requirement.
Separate Nut Orders
Nut-only orders can be reviewed by grade, size, thread, quantity, finish, marking, packing and document request.
One Nut per Stud
One-nut configurations should state the Stud Bolt specification, thread, quantity and packing method before quotation.
Two Nuts per Stud
Two-nut configurations may be reviewed when requested. Nut grade, quantity and matched Stud Bolt details remain purchase-specification inputs.
Matched Stud Bolt Orders
Matched orders can be reviewed with ASTM A193 Stud Bolt requirements, while matching remains controlled by the purchase specification.
Custom Thread or Dimension Review
Custom thread and dimensional requirements can be reviewed from drawings or specifications. Feasibility is subject to order review.
Grade Review
Nut grade, matching Stud Bolt specification and grade, thread, dimensions, quantity, finish and document requirements should be confirmed from the purchase specification.
| ASTM A194 Nut Grade | What the Buyer Should Confirm | Related Bolting Context |
|---|---|---|
| Grade 2H | Confirm grade, nut form, size, thread, finish, marking, quantity and document request. | May be discussed with alloy-steel bolting context such as ASTM A193 B7 / B7M material context when specified. |
| Grade 2HM | Confirm grade and order-specific requirements without treating Grade 2H and 2HM as interchangeable. | Related material pages provide context only and do not define matching requirements. |
| Grade 7 | Confirm purchase specification, service conditions, finish, marking and inspection request. | Use supporting material references only where the buyer specification calls for them. |
| Grade 7M | Confirm grade designation, dimensional requirements, thread details and document request. | Do not treat Grade 7 and 7M as automatically interchangeable. |
| Grade 8 | Confirm stainless grade context, thread, quantity, surface condition and document request. | May be discussed with stainless bolting context such as ASTM A193 B8 / B8M material context when specified. |
| Grade 8M | Confirm grade, thread, finish, matched Stud Bolt inputs and inspection request. | Do not treat Grade 8 and 8M as automatically interchangeable. |
| Other ASTM A194 grades | Other ASTM A194 grades may be reviewed according to the purchase specification and supply confirmation. | Supply, documents and inspection remain order-specific. |

Special Coatings or Plating
Special coatings or plating are subject to grade, dimensions, quantity and process feasibility.
Stainless Surface Condition
Stainless surface condition can be discussed where relevant, but grade must not be inferred from visible surface finish.
Buyer-Specified Finish
Buyer-specified finish requirements should be stated before quotation and reviewed with order quantity and delivery context.
Matched Finish Review
Compatibility between nut, Stud Bolt and washer finishes should be reviewed from the purchase specification.
Order Confirmation
Availability of material, finish, marking and documents remains subject to order confirmation.
